Prompted by this thread, I took advantage of yesterdays' sunshine & hopped on a train to Hornsey.
I'm happy to say that the former Lotus showroom/office is still intact and in good condition. The five-windowpane frontage is again visible - complete with a large Lotus Seven graphic. The Club Lotus plaque placed on the building in 1984 is still firmly in place.
The Railway Hotel, most recently a rather dodgy 'Funky Brownz', is currently empty and the internals are being stripped.
Anyhow, I spent an interesting half-hour matching up the photos from 'Simpatico's posting above.
